Description

  The present invention relates to a vehicle seat control device, and more particularly to a vehicle seat control device having a seat support adjustment function for adjusting a side support of a vehicle seat.

  In turning and the like, a force in the vehicle width direction acts on the occupant, so that the driving posture can be stabilized by adjusting the side support of the vehicle seat. Therefore, a vehicle seat control device that adjusts the side support of the vehicle seat according to the traveling state has been proposed.

For example, in the technique described in Patent Document 1, it is proposed to control the side support by detecting the lateral acceleration (acceleration in the vehicle width direction) of the vehicle. Specifically, there are two types of hold time held by the side support (time held by the side support), and a short hold time is detected when lateral acceleration exceeding the reference value is continuously detected for more than the reference time. The side support is controlled to the hold position until the time elapses, and when intermittent lateral acceleration exceeding the reference value is detected multiple times within a predetermined time, the side support is switched from the short hold time to the long hold time. Control to hold position.
Japanese Patent No. 2750943

  However, in the technique described in Patent Document 1, the lateral acceleration of the vehicle is detected to control the side support. However, since the driving amount and the driving speed of the side support are not taken into consideration, the support performance is further improved. There is room for improvement in control.

  The present invention has been made in consideration of the above facts, and an object thereof is to control the side support of the vehicle seat in accordance with the traveling state.

In order to achieve the above object, the invention described in claim 1 includes an adjusting means for adjusting a support angle by a side support of a vehicle seat for holding an occupant, an acquiring means for acquiring a lateral acceleration generated in the vehicle, Based on the support angle predetermined for each lateral acceleration, support angle setting means for setting the support angle according to the lateral acceleration acquired by the acquisition means, and predetermined for each predetermined movement section of the side support Adjustment for setting the adjustment speed for a movement section between the current support angle adjusted by the adjustment means and the support angle set by the support angle setting means based on the adjustment speed by the adjustment means. and speed setting means, the adjustment rate set by the adjustment speed setting means, the support angle Is characterized in that it comprises a control means for controlling said adjusting means so that the support angle set by the constant means.

  According to the first aspect of the present invention, the adjusting means adjusts the support angle for holding the occupant by the side support of the vehicle seat. For example, the support angle is adjusted by narrowing or widening the side support with an actuator or the like.

The acquisition means, lateral acceleration generated in vehicles (vehicle width direction of the acceleration) is obtained. The acquisition means calculates the lateral acceleration based on the detection results of the vehicle speed detection means for detecting the vehicle speed and the steering angle detection means for detecting the steering angle, as in the fifth aspect of the invention. The calculation result may be acquired from the map, or the map information acquisition for acquiring the detection result of the vehicle speed detecting means for detecting the speed of the vehicle and the map information of the travel destination of the vehicle as in the invention of claim 6. Based on the acquisition result of the means, the estimation result of the estimation means for estimating the lateral acceleration may be acquired.

Further, the support angle setting means sets a support angle according to the lateral acceleration acquired by the acquisition means based on a side support angle predetermined for each lateral acceleration, and the adjustment speed setting means sets the side support for each predetermined movement section of the side support. The adjustment speed by the adjustment means is set for the movement section between the current support angle adjusted by the adjustment means and the support angle set by the support setting means based on the adjustment speed by the adjustment means determined in advance. .

Then, in the control means, the adjustment means is controlled so that the support angle set by the support angle setting means becomes the adjustment speed set by the adjustment speed setting means.

That is, by adjusting the side support by setting the support angle and the adjustment speed of the side support according to the lateral acceleration generated in the vehicle , the side support of the vehicle seat can be controlled according to the running state. In other words, by setting not only the support angle but also the adjustment speed, it is possible to give the occupant an optimal feeling of holding that matches the traveling state of the vehicle and to hold the occupant in a posture that makes driving easier.

For example, the support angle setting means may set the support angle such that the support angle becomes narrower as the lateral acceleration increases , as in the invention described in claim 2.

Further, the adjustment speed predetermined for each predetermined movement section is set to be faster in the movement section having a wider angle than the movement section having a narrow support angle, as in the third aspect of the invention. You may do it. The adjustment speed setting means may set the adjustment speed to be higher as the support angle set by the support angle setting means is narrower or the adjustment amount is larger, as in the invention described in claim 4. Good.

As described above, according to the present invention, the side support is adjusted by setting the support angle and the adjustment speed of the side support according to the lateral acceleration generated in the vehicle , so that the side support of the vehicle seat can be adjusted according to the running state. There is an effect that it can be controlled.

  Hereinafter, an example of an embodiment of the present invention will be described in detail with reference to the drawings. FIG. 1 is a diagram illustrating an example of a vehicle seat to be controlled by the vehicle seat control apparatus according to the embodiment of the present invention.

  In the vehicle seat 10 to be controlled by the vehicle seat control apparatus according to the embodiment of the present invention, the side support 12 narrows the seat back side of the vehicle seat with the rotation axis as shown in the arrow A direction in FIG. The occupant's support amount can be adjusted by rotating in the direction or the direction of expansion. The rotation of the side support 12 is controlled by the vehicle seat control device 14 (FIG. 2). That is, by controlling the rotation of the side support 12 by the vehicle seat control device 14, the movement of the occupant in the lateral direction (vehicle width direction) due to acceleration generated by turning or the like is suppressed. Specifically, the vehicle seat control device 14 according to the embodiment of the present invention acquires the lateral acceleration generated in the vehicle as the traveling state of the vehicle, and controls the rotation of the side support 12 according to the acquired acceleration.

  FIG. 2 is a block diagram showing a configuration of the vehicle seat control device 14 according to the embodiment of the present invention.

  The vehicle seat control device 14 according to the embodiment of the present invention includes a side support actuator 18 for rotating the side support 12 of the vehicle seat 10 in the direction of arrow A in FIG. The side support 12 is adjusted by controlling the rotation of the side support 12 of the vehicle seat 10 by controlling the actuator 18.

  The side support actuators 18 are provided in the vehicle seat 10 such as a driver seat and a passenger seat, respectively, and include a motor 20 and a Hall IC 22. In FIG. 2, only one side support actuator 18 is shown. However, since the side support 12 of the vehicle seat 10 has two sides of each vehicle seat 10, the side support actuator 18 has two for each vehicle seat 10. One is provided.

  The motor 20 of the side support actuator 18 rotates the side support 12 in the direction of arrow A in FIG. At this time, the rotation amount of the side support 12 is detected by detecting the rotation of the motor 20 by the Hall IC 22 and the detection result is output to the vehicle seat control unit 16, and the vehicle seat control unit 16 outputs a pulse output from the Hall IC 22. Etc., the position of the side support 12 is detected.

  Further, the vehicle seat control unit 16 has a vehicle stability control (VSC) that controls the running vehicle posture based on the steering angle detected by the steering angle sensor 26, the wheel speed detected by the wheel speed sensor 28, and the like. A control unit 24 is connected, and detection results of the steering angle sensor 26 and the wheel speed sensor 28 input to the VSC control unit 24 can be acquired. In the present embodiment, the detection results of the steering angle sensor 26 and the wheel speed sensor 28 can be acquired from the VSC control unit 24, but the present invention is not limited to this. For example, a VDIM (Vehicle Dynamics Integrated Management) control unit Alternatively, detection results of the steering angle sensor 26 and the wheel speed sensor 28 may be acquired from various control units such as an EFI (Electronic Fuel Injection) control unit. In the present embodiment, the vehicle seat control unit 16 can acquire the detection result of the wheel speed sensor 28. However, the present invention is not limited to this, and the detection result of the vehicle speed sensor is acquired instead of the wheel speed sensor 28. It may be possible.

  The vehicle seat control unit 16 calculates the lateral acceleration generated in the vehicle based on the steering angle and the wheel speed acquired from the VSC control unit 24, and according to the calculated lateral acceleration, the rotation angle of the side support 12 (support Angle) and the rotational speed of the side support 12 is set based on the set support angle to control the drive of the side support actuator 18.

  Specifically, the vehicle seat control unit 16 sets the support angle α0 of the side support 12 when the calculated lateral acceleration G is G0 ≦ G <G1, and the lateral acceleration G is G1 ≦ G <G2. The support angle α1 of the side support 12 is set to the support angle α1 of the side support 12 when the lateral acceleration G is G2 ≦ G.

  In addition, as shown in FIG. 3, the moving section of the side support 12 detected from the set support angle and the support angle detected by the vehicle seat control unit 16 from the detection result of the Hall IC 22 is larger than the support angle α1 ( In the case of the intervals α1 and α0 shown in FIG. 3 where the side support 12 is wider than α1, the motor 20 is rotated with the rotational speed set to β2, and the interval smaller than the support angle α1 (FIG. 3). In the case where the side support 12 is narrower than α1), the rotational speed β1 is set to rotate the motor 20, and in the case of the support angle α0, the rotational speed β0 is set. Then, the motor 20 is rotated. That is, in this embodiment, when moving from a wide support angle α0 to α1, the initial reaction of the side support is improved by setting to move at a faster speed than when moving from the support angle α1 to α2. However, the lower the support angle that is set or the larger the adjustment amount of the support angle, the higher the rotation speed may be set.

  At this time, the vehicle seat control unit 16 controls the support angle of the side support 12 by controlling the number of pulses of the pulse current applied to the motor 20, the current application time, and the like, and controls the motor 20 by PWM control. 12 rotational speeds are controlled.

  The lateral accelerations G0, G1, and G2 are G0 = 0 and G1 <G2, and the support angles α0, α1, and α2 are α0 = 0 (predetermined reference angle) and α1 <α2, and the rotational speeds β0, β1. , Β2 is β0 = 0 and β1> β2, but is not limited thereto.

  In step 204, it is determined whether or not the moving section of the side support 12 is between the support angles α0 to α1. If the determination is affirmative, the process proceeds to step 206, and if the determination is negative, the process proceeds to step 208.

  In step 206, the rotational speed β2 is set and the routine proceeds to step 214. In step 208, it is determined whether or not the moving section of the side support 12 is a section of the support angle α1 or more. If the determination is affirmative, the process proceeds to step 210, and if the determination is negative, the process proceeds to step 212.

  In step 210, the rotational speed β1 is set and the process proceeds to step 214. In step 212, the rotational speed β0 is set and the process proceeds to step 214.

  In step 214, the motor 20 is rotated at the set rotational speed in the set support angle direction, and the process proceeds to step 216.

  In step 216, the support angle α of the side support 12 is detected by detecting the position of the motor 20, the process proceeds to step 216, and it is determined whether or not it has moved to the set support angle. If the determination is negative, the process returns to step 202 and the above-described processing is repeated. The motor 20 is rotated until the set support angle is reached. The motor rotation process is returned, and the process proceeds to step 116 in FIG.
